18 EC4-200 network modules
The EASY205-ASI, EASY221-CO, EASY204-DP, EASY222-DN
network modules enable you to connect the EC4-200 as a slave to
ASI, CAN, PROFIBUS-DP or DeviceNet (a table 20) networks.
The controller can also be integrated as a station in an easy-NET
network.
The type of data exchange between master and network modules
is shown in table 20.
Table 20: Overview of network modules
Table 21: Manuals on the network modules
EASY205-ASI
Cyclic data exchange
The master sends 8 bits to the EASY205-ASI network module
connected to the EC4-200: 4 bits of output data and 4 parameter
bits. It receives 4 bits of input data from the EC4-200.

The network modules in conjunction with the easy800 are
described in detail in separate manuals (a table 21).
These manuals also apply to the EC4-200 connected to
the network modules since this controller operates exactly
like the easy800. The following sections on the individual
network modules therefore only cover the differences
between them and any particular procedures.
